要计算四年级下册数学75×46+75×55-75，我们可以采用分步骤计算的方法。首先，计算75×46和75×55的结果，然后将这两个结果相加，最后将75减去得到的和即可。
具体做法如下：
1. 计算75×46，首先将75拆解成50+25，然后分别计算50×46和25×46的结果，并将它们相加。50×46 = 2300，25×46 = 1150，所以75×46 = 2300+1150 = 3450。
2. 计算75×55，同样将75拆解成50+25，然后分别计算50×55和25×55的结果，并将它们相加。50×55 = 2750，25×55 = 1375，所以75×55 = 2750+1375 = 4125。
3. 将步骤1和步骤2中得到的结果相加，即3450+4125 = 7575。
4. 最后，将步骤3中得到的结果7575减去75，得到最终计算结果7500。
因此，四年级下册数学75×46+75×55-75的计算结果为7500。
《挑山工》主要叙述了一个作者在登泰山时发现挑山工登山的过程，走的路程比游客们多一倍，但速度并不比游客慢，经过交谈得知其登山的速度之快在于挑山工的专注的故事。
《挑山工》是冯骥才在1981年写的泰山见闻之一，也是泰山题材的著名散文之一，1983年选入全国高中语文课本，后选入小学语文课本。
学者王克煜将这篇散文和姚鼐的《登泰山记》、李健吾的《雨中登泰山》、杨朔的《泰山极顶》并称为现代泰山四大著名散文。
他在文中没有着墨于泰山的雄姿和胜景，而是把目光投向挑货上山的山民，描绘了他们艰辛的劳作和惊人的毅力，赞颂了挑山工坚韧不拔的攀登精神。
